A field experiment was conducted at Research Farm, College of Agriculture, Pune during kharif 2023. The object of this experiment was to study comparative efficiency of phosphorus application through phosphorus rich organic manure (PROM), single super phosphate and diammonium phosphate (DAP) for soybean on enzyme activities and nutrient availability in highly calcareous soil. This experiment consisted of two organic sources (PROM and vermicompost) and two inorganic sources of phosphorus (SSP and DAP) along with their levels @ 50, 75 and 100 % imposed for soybean in highly calcareous soil.

Abstract:

The purpose of the work is to study the effect and aftereffect of various types and rates of fertilizers on the change in the main fertility indicators of gray forest soil, as well as the productivity of the crop rotation link. The experiments were carried out in the grain-row unit (spring wheat - corn - spring wheat - peas) of a nine-field grain-herb-row crop rotation. The scheme of the experiment provided for the study of the following options: the calculated doses of mineral fertilizers for the formation of 4 t/ha of spring wheat grain, 40 t/ha of green mass of corn, 3 t/ha of pea grain, th

Understanding the soil nutrient content varied with the soil depth is one of the most important aspects of every crop husbandry practice and information about the soil nutrient status of a certain area is very important for nutrient management programs. Considering this, a study was carried out in order to find out the depth-wise status of soil pH, soil organic matter and macronutrients in the paddy-wheat cropping system of the different areas of Rupandehi District of Nepal. The study was undertaken from April, 2019 to May 2019 immediately after the harvesting of the wheat crop. Altogether 108

Abstract:

The redgram-foxtail millet intercropping system is a sustainable agricultural practice that optimizes resource use, with redgram enriching soil fertility through nitrogen fixation and foxtail millet providing high yields in drought-prone, low-nutrient soils. Foxtail millet is highly valued for its nutritional benefits, including being rich in proteins, fiber, and essential minerals, while also being drought-tolerant and suitable for cultivation in semi-arid regions, making it crucial for food security and climate-resilient farming.

In order to establish the mechanism that results in higher strength, the effects of a variety of condensed sodium phosphates (NaPO3)n, (NaPO3)n · Na2O, Na5P3O10, and (NaPO3)3 were studied. The influence of these additions on the kinetics of hydration was studied using isothermal calorimetry. The phosphatic additions enhanced reactivity, but x-ray diffraction analyses did not reveal evidence of new crystalline phosphate-containing hydration products. Mi

Abstract:

Phosphogypsum, a byproduct of phosphoric acid production in the fertilizer industry, is an environmentally friendly source of calcium sulfate for controlling the setting time in cements, replacing gypsum. However, as it is a waste product, it can contain impurities such as F- and P2O5, which may prolong the setting time beyond the desired duration and reduce initial mechanical strength. A solution to this problem is the use of hydration/strength accelerators, of which several types are available. Considering cost, sodium chloride can be an attractive option. However, it is known that chlorides
